前言

最近发现一个比较好玩的东东，一个不需要 mock 并且匹配正则的接口直接转发到后端地址的小工具。

install

yarn create @lowcoding/mock

start

yarn start

lowcode-mock 默认支持跨域，前端项目中可不必再配置代理，直接请求 lowcode-mock 起的服务即可。

mock

import KoaRouter from 'koa-router'import proxy from '../middleware/Proxy'import { delay } from '../lib/util'let Mock = require('mockjs')let Random = Mock.Random
const router = new KoaRouter()router.get('/your-mock-api', (ctx) => {    ctx.body = '你的第一个mock接口'})module.exports = router

根据 YAPI 生成 mock

根据 JSON 生成 mock

通过 JSON 数据生成的 mock 接口需要手动修改路由地址。

根据字段类型或字段名称生成特定的 mock 数据

"yapi-code.mockKeyWordLike": {        "icon": "Random.image('48x48')",        "img":"Random.image('48x48')",        "image":"Random.image('48x48')",        "code": "200&&number",        "name":"'模糊匹配后生成的mock'"    },    "yapi-code.mockKeyWordEqual": {        "message": "'这是一条精确的mock'",        "total": 200,    },    "yapi-code.mockString": "Random.cword(5, 6)",    "yapi-code.mockBoolean": "Random.boolean()",    "yapi-code.mockNumber": "Random.natural(100,1000)"

const json = {    code: 100,    message: '请求成功',    result: {        list: [            {                code: '注意这是一个字符串的code',                name: '张三',                icon: '',                actived: false,            },        ],        total: 0,    },}

.get(`xxxxx`, async (ctx, next) => {        const list1 = []        for (let i = 0; i < 3; i++) {            list1.push({                code: Random.cword(5, 6),                name: '模糊匹配后生成的mock',                icon: Random.image('48x48'),                actived: Random.boolean(),            })        }        ctx.body = {            code: 200,            message: '这是一条精确的mock',            result: { list: list1, total: 200 },        }    })

{    "code": 200,    "message": "这是一条精确的mock",    "result": {        "list": [            {                "code": "八别因教者活",                "name": "模糊匹配后生成的mock",                "icon": "http://dummyimage.com/48x48",                "actived": true            },            {                "code": "毛着何工时白",                "name": "模糊匹配后生成的mock",                "icon": "http://dummyimage.com/48x48",                "actived": false            },            {                "code": "县称县单下外",                "name": "模糊匹配后生成的mock",                "icon": "http://dummyimage.com/48x48",                "actived": true            }        ],        "total": 200    }}

延时

import KoaRouter from 'koa-router'import proxy from '../middleware/Proxy'import { delay } from '../lib/util'let Mock = require('mockjs')let Random = Mock.Random
const router = new KoaRouter()router.get('/delay', (ctx) => {    delay(3) // 3 秒后返回结果    ctx.body = 'delay'})

可用于测 loading 效果。

http 异常状态码

router.get('/httpError', (ctx) => {    ctx.status = 401    ctx.body = 'http 401'})

代理

router.get('/proxy', proxy('https://github.com/wjkang/lowcode-mock'), (ctx) => {    ctx.body = 'https://github.com/wjkang/lowcode-mock'})

来自 /proxy 的请求转发到 https://github.com/wjkang/lowcode-mock/proxy ，用于后端接口可联调的时候跳过本地 mock，转发请求到后端接口。

router.all(new RegExp('^/lowcode/mock/(|^$)'), proxy('https://github.com/wjkang/lowcode-mock'))

不需要 mock 并且匹配正则的接口直接转发到后端地址。
